Europe on Solar Energy. The department for Solar PV technologies is dedicated to all the technologies involved in photovoltaic silicon. From material (process development of Solar grade silicon by purification of metallurgical grade silicon), cells (Silicon solar cells), to modules (development of new processes for module manufacturing). There are presently more than 120 people working in this department. There is also a technological structure at the CEA-INES center dedicated to develop heterojunction silicon PV cells production processes suitable for industrialization. This unit called “LabFab” has industry like capability to produce high volume of large area SHJ Cells. In the NEXT-BASE project, the material, cells, module laboratories as well as the production pilot line will be participating actively.
